Which radars cover Aliso Viejo?
The closest NEXRAD Doppler radar is KSOX (Santa Ana Mountains, CA), about 17 miles north-northeast. Radar beams climb as they travel, so the height of the lowest scan over town decides how low in a storm the radar can see.
| Radar | Distance | Lowest beam over Aliso Viejo | View |
|---|---|---|---|
| KSOX Santa Ana Mountains, CA | 17 mi north-northeast | 900 ft | Excellent — the lowest scan sees close to the ground |
| KNKX San Diego, CA | 60 mi southeast | 4,600 ft | Good — most storms and steady rain or snow show clearly |
| KVTX Los Angeles, CA | 101 mi northwest | 9,800 ft | Fair — the beam can pass over shallow snow and low-level rotation |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
